W29C102 64K x 16 CMOS FLASH MEMORY GENERAL DESCRIPTION The W29C102 is a 1-megabit, 5-volt only CMOS flash memory organized as 64K x 16 bits. The device can be programmed and erased in-system with a standard 5V power supply. A 12-volt VPP is not required. The unique cell architecture of the W29C102 results in fast program/erase operations with extremely low current consumption (compared to other comparable 5-volt flash memory products). The device can also be programmed and erased using standard EPROM programmers.

CE is used for device selection. When CE is high, the chip is de-selected and only standby power will be consumed. OE is the output control and is used to gate data from the output pins. The data bus is in high impedance state when either CE or OE is high. Refer to the timing waveforms for further details. Page Write Mode The W29C102 is programmed on a page basis. Every page contains 128 words of data. If a word of data within a page is to be changed, data for the entire page must be loaded into the device. Any word that is not loaded will be erased to "FFh" during programming of the page. The write operation is initiated by forcing CE and WE low and OE high. The write procedure consists of two steps. Step 1 is the word-load cycle, in which the host writes to the page buffer of the device. Step 2 is an internal programming cycle, during which the data in the page buffers are simultaneously written into the memory array for non-volatile storage. During the word-load cycle, the addresses are latched by the falling edge of either CE or WE, whichever occurs last. The data are latched by the rising edge of either CE or WE, whichever occurs first. If the host loads a second word into the page buffer within a word-load cycle time (TBLC) of 200 S, after the initial word-load cycle, the W29C102 will stay in the page load cycle. Additional words can then be loaded consecutively. The page load cycle will be terminated and the internal programming cycle will start if no additional word is loaded into the page buffer. A7 to A15 specify the page address. All words that are loaded into the page buffer must have the same page address. A0 to A6 specify the word address within the page. The words may be loaded in any order; sequential loading is not required. In the internal programming cycle, all data in the page buffers, i.e., 128 words of data, are written simultaneously into the memory array. The typical programming time is 5 mS. The entire memory array can be written in 2.6 seconds. Before the completion of the internal programming cycle, the host is free to perform other tasks such as fetching data from other locations in the system to prepare to write the next page. Software-protected Data Write The device provides a JEDEC-approved optional software-protected data write. Once this scheme is enabled, any write operation requires a series of three-word program commands (with specific data to a specific address) to be performed before the data load operation. The three-word load command sequence begins the page load cycle, without which the write operation will not be activated. This write scheme provides optimal protection against inadvertent write cycles, such as cycles triggered by noise during system power-up and power-down. The W29C102 is shipped with the software data protection enabled. To enable the software data protection scheme, perform the three-word command cycle at the beginning of a page load cycle. The device will then enter the software data protection mode, and any subsequent write operation must be preceded by the three-word program command cycle. Once enabled, the software data protection will remain enabled unless the disable commands are issued. A power transition will not reset the -3- Publication Release Date: March 1998 Revision A3 W29C102 software data protection feature. To reset the device to unprotected mode, a six-word command sequence is required. See Table 3 for specific codes and Figure 10 for the timing diagram. Hardware Data Protection The integrity of the data stored in the W29C102 is also hardware protected in the following ways: (1) Noise/Glitch Protection: A WE pulse of less than 15 nS in duration will not initiate a write cycle. (2) VDD Power Up/Down Detection: The programming operation is inhibited when VDD is less than 2.5V. (3) Write Inhibit Mode: Forcing OE low, CE high, or WE high will inhibit the write operation. This prevents inadvertent writes during power-up or power-down periods. (4) VDD power-on delay: When VDD has reached its sense level, the device will automatically time-out 5 mS before any write (erase/program) operation. Data Polling (DQ7 & DQ15)- Write Status Detection The W29C102 includes a data polling feature to indicate the end of a programming cycle. When the W29C102 is in the internal programming cycle, any attempt to read DQ7 and/or DQ15 of the last word loaded during the page/word-load cycle will receive the complement of the true data. Once the programming cycle is completed. DQ7 will show the true data. Toggle Bit (DQ6 & DQ14)- Write Status Detection In addition to data polling, the W29C102 provides another method for determining the end of a program cycle. During the internal programming cycle, any consecutive attempts to read DQ6 and/or DQ14 will produce alternating 0's and 1's. When the programming cycle is completed, this toggling between 0's and 1's will stop. The device is then ready for the next operation. 5-Volt-only Software Chip Erase The chip-erase mode can be initiated by a six-word command sequence. After the command loading cycles, the device enters the internal chip erase mode, which is automatically timed and will be completed in 50 mS. The host system is not required to provide any control or timing during this operation. Product Identification The product ID operation outputs the manufacturer code and device code. Programming equipment automatically matches the device with its proper erase and programming algorithms. The manufacturer and device codes can be accessed by software or hardware operation. In the software access mode, a six-word command sequence can be used to access the product ID. A read from address 0000H outputs the manufacturer code (00DAh). A read from address 0001H outputs the device code (004Fh). The product ID operation can be terminated by a three-word command sequence. In the hardware access mode, access to the product ID is activated by forcing CE and OE low, WE high, and raising A9 to 12 volts. -4- W29C102 TABLE OF OPERATING MODES Operating Mode Selection (VHH = 12V) MODE CE Read Write Standby Write Inhibit Output Disable 5-Volt Software Chip Erase Product ID VIL VIL VIH X X X VIL VIL VIL OE VIL VIH X VIL X VIH VIH VIL VIL WE VIH VIL X X VIH X VIL VIH VIH AIN AIN X X X X AIN PINS ADDRESS Dout Din High Z High Z/DOUT High Z/DOUT High Z DIN Manufacturer Code 00DA (Hex) Device Code 004F (Hex) DQ.
